Student will learn the structure of a flow proof.

Student will learn the structure of a statement-reason (two-column) proof.

Meant as an introduction to constructing geometric proofs, both in the flow proof style and the two-column, or statement-reason style. As an introductory lesson this packet only includes short proofs with some of the basic structure provided.

Tutorial

This packet shows a flow proof and a statement-reason proof (sometimes called two-column proof) for the following proof.

Discusses how geometric proof is different from mathematics up until this point. Compares the process of constructing a geometric proof to working your way through a maze.

This example of a flow proof is meant as an introduction to the format of geometric proof. The structure of the proof, as well as a list of reasons are given to the student for this introductory proof.

This is the same proof as above, but it is presented in the statement-reason format. It is meant as introduction to the two-column proof format.
